Abstract: A recording/reproducing device using a magneto-optical disc as a recording medium having a holder for holding a magneto-optical disc and moving the magneto-optical disc between a disc unloading position and a disc loading position, a turntable for rotating the magneto-optical disc, an optical pickup for casting a light beam onto a signal recording surface of the magneto-optical disc, a magnetic head arranged to face the optical pickup on the opposite sides side of the magneto-optical disc and moving toward and away from the magneto-optical disc, and a rotating ejection lever positioned on a base for ejecting the magneto-optical disc held by the holder. Since the ejection lever is arranged on the side of the base where the optical pickup is arranged, the space within the device body is effectively used, thus realizing miniaturization.

Abstract: A recording and/or reproducing apparatus for magneto-optical disc includes a head supporting mechanism and a movement mechanism. The head supporting mechanism includes a supporting member disposed above a holder in such a manner to oppose an optical pick-up and provided at one end side with a magnetic head to move the supporting member between recording position at which the magnetic head supplies external magnetic field to the magneto-optical disc held by the holder and non-recording position above the recording position and at which the magnetic head is spaced with respect to the magneto-optical disc.

Abstract: A recording and/or reproducing apparatus includes a base member at least having a rotation driving mechanism for rotationally driving a disc housed in a disc cartridge, a holder into which is inserted the disc cartridge and an ejection lever formed by an elastically flexible lever. The holder is mounted for movement between a first position in which the disc inserted in the disc cartridge is loaded on the rotation driving mechanism and a second position in which the disc housed in the disc cartridge is spaced apart from the rotation driving mechanism. The second position is higher in level than the first position. The ejection lever is elastically flexed by the disc cartridge inserted into the holder from a position protruded into the holder to the position extending along the back side of the holder. When elastically flexed to the position extending along the back surface of the holder, the ejection lever is engaged with the holder moved to the first position.

Abstract: A recording and/or playback apparatus using a disc cartridge that accommodates a recording medium such as an optical disc includes a holder, a recording and/or playback section, and a moving mechanism.
